Problems solved by technology

[0002] Due to the high power consumption of the lamps and lanterns in the stage lighting and audio performance, and early use of thyristors to dim the stage lamps, the thyristors are located on the ground, so they all use a single phase for dimming relative to the lamps, so the amount of copper used is large.

Abstract

The invention relates to a single-phase box body power supply structure branched by three phases, which comprises a box body, air switches and a 32A plug, wherein the end surface of one end of the box body is provided with the 32A plug; the position, close to the 32A plug, inside the box body is provided with the air switches whose upper end surfaces are exposed at the upper side of the box body; a row of single-phase power supply sockets are arranged between the upper end surface of the box body and the air switches and the other end of the box body; and the box body at one sides of the single-phase power supply sockets is provided with a plurality of indicating lamps. If any of the single-phase power supply sockets overloads, the air switches cut off the power supply to protect the power supply. The structure is compact and reasonably, overload protection can be carried out on the power supply via the air switches, installation is convenient, and resources are integrated.

Description

technical field [0001] The invention relates to the field of three-phase power supply structures, in particular to a box-body power supply structure in which the three-phase branch line is single-phase. Background technique [0002] Due to the high power consumption of the lamps and lanterns in the stage lighting and audio performance, and early use of thyristors to dim the stage lamps, the thyristors are located on the ground, so they all use a single phase for dimming relative to the lamps, so the amount of copper used is large. [0003] Today, the appearance of lamps and lanterns has been greatly changed. It has built-in transformers, drive circuit boards, and uses advanced bulbs such as LEDs to generate light sources, and uses dmx-512 for control. It only needs to supply power to it, and no single-phase dimming power supply is required. Co-response, so if the early single-phase long-line solution is used, it is an unreasonable waste of resources. If the single-phase powe...
